This question asks us to look at the graph provided and answer whether or not we think some statements that they've made about the graph are correct.
00:11
We're also asked to explain our answers.
00:15
So the first statement that they make is that food allergies and children are on the rise.
00:21
So when we're looking at this graph, we have the year on the x axis and the percentage of children with allergies on the y axis.
00:30
The black line shows children under five years old, and the red line shows children ages 5 to 17.
00:39
So when we look at the graph also, the scaling on this is really small.
00:45
So about here on the graph is going to be 5 % of children.
00:51
So can we tell from this graph if allergies are really on the rise? i think the answer is no.
01:02
There's some wobbling of this data and perhaps a really gradual trend of increasing.
01:10
But if we were to look at this scaled to the full range, so from zero to 100%, this line would look totally flat.
01:20
So i don't think there's any meaningful increases and the number of children with food allergies in shown in this graph.
01:34
Okay, part b.
01:38
In a group of 100 children age 5 or younger, we would expect about 10 out of 100 to have allergies...
